I used to watch it as a child, but now I don't. I stopped around Generation 2, yet I still watched the movies. In my humblest opinion, though, the Generation 1 theme song is without a doubt, the best song out of the entire theme songs.

Watching through the fourth season right now, and it just seems to be getting better with the exception of Todd showing up for the Articuno story arc and being the most incompetent photographer I've ever seen. Which just frustrated me the whole time.
